Repeat units: consistency matters more than strength
On a townhouse phase, the same footing, ground beam and slab design repeats unit after unit. The engineer cares that cube results do not drift between the first block and the fortieth. We batch the substructure and superstructure mixes from a fixed design on OPC and GGBS, so the same order gives the same concrete each time.
A typical townhouse ground slab might be 30 m³, which is three truckloads. Keep the pour continuous and the cold joint question disappears.
For each phase, we keep a record of the mix design reference against every delivery ticket, so the consultant can trace any cube back to the batch it came from.
Ground beside irrigated land
The district is inland, but plots next to the golf course and landscaped areas sit in soil that is watered every day. Moisture in the ground around a footing is something the soil investigation should look at, because it can bring dissolved salts up toward buried concrete. If the report flags it, the consultant may raise the exposure class, and we adjust the substructure mix to match: lower water/cement ratio, more GGBS.
Blinding goes down first so the reinforcement sits on a clean surface with the right cover.
Hardscape and the summer pour
Driveways, terraces and pool decks are thin and exposed. A fibre-reinforced mix limits early cracking, and an early-morning pour avoids placing a slab into the hottest part of the day. For a site about 12 km from Al Quoz via Al Qudra Road or Umm Suqeim Street, we set the retarder dose for travel time plus the time spent waiting on site.
Questions from DAMAC Hills sites
- Who decides when trucks can enter DAMAC Hills?
- The developer and community management control access and delivery hours. Check with them first and book the pour inside the window they give you.
- Can one pump reach several townhouse units from one position?
- A 57 m boom often covers more than one unit in a row. We look at the layout and tell you where to set it up.
- What mix goes under the footings?
- Blinding, a lean concrete layer that gives the steel fixers a clean, level surface and protects the bottom cover.
